To be honest, I haven't been able to give RPM a fair cycle b/c of vacation times. I've used it as a preworkout but I didn't use it enough to get the cumulative effects from it. It is possible my mind would change, but right now if I had to choose just 1....

GABA is definitely one of my favorite supps...use it as a sleep aid...works great. let's see...since this doesn't include other things such as BCAA's...I'm damn near stuck on this one...categories would make this simpler, lol.

RPM lights a fire under my ass and is a definite help while dieting.
Hunger control, energy, motivation, slight psychotic feeling.

psychotic?? yeah i took a dose and threatened some guys life at a red light the other day for cutting me off on the way to the gym. i was gonna let it go until he flicked a cig out the window and i watched it bounce up into the grill of my car. i guess psychotic is accurate

RPM hands down the best. Its the best thing I have ever used for fat loss so far. It actually makes me look forward to cardio/fat loss workouts!. I need to start it up again but can't spare the cash right now. Looks like I'll have to knock that Beyotch Zombie off my f*cking corner!

damn, rpm must be sick....everyone's lovin it. i woulda thought alot of people woulda said like p-slin or leviathon

I've tried both and am currently using Hot Rox and RPM, but Hot Rox Extreme kicks RPM's ass as a fat-burner. RPM gives me more of a focused-feeling, and definitely makes me sweat a lot, but Hot Rox Extreme seems to melt abdominal fat and suppresses appetite just enough, but not overly suppressive.

Hot Rox Extreme =

Plus, one bottle lasts forever, as ONE PILL A DAY has such a strong effect that the full 4 per day serving would be mind blowingly powerful. I take 5 RPM to equal the effectiveness of 1 HRXE pill.
